Wastewater Treatment

Data Table


The LOTT Clean Water Alliance is a non-profit corporation providing wastewater management services for homes and businesses in the Lacey, Olympia, and Tumwater area. LOTT is responsible for two major wastewater treatment functions: handling flow management and long-range planning, and coordinating a relatively new service – the production of reclaimed water.

LOTT treated an average of 13.76 million gallons per day (mgd) of wastewater in 2021, down from a peak of 14.62 mgd in 2017.

Reclaimed water production at LOTT’s Budd Inlet and Martin Way treatment facilities has increased since production began in 2004. In 2021 LOTT produced 1.74 million gallons of Class A reclaimed water per day at the two facilities.

"Class A" is a designation from the State Dept. of Ecology for water clean enough for public contact and most uses, except drinking. The City of Tumwater is one of the region’s largest consumers of reclaimed water, using up to 600,000 gallons of water per day for irrigation at the Tumwater Valley Golf Course.
